I had one thunder down the road from behind me when I was at high school. Thinks I was not expecting- the slapping of massive feet as it pegged it down the street.
I lived in suburban Edinburgh ( Portobello). It came and hung out on a row of houses for a month or so.
The rspb tried to catch it repeatedly. It kept jumping fences and they had to ask each house for permission to chase it.
The word on the street was a fox got it in the end. 😭
I asked my students about their pets one day. Cats, dogs, fish and one girl had a couple of peacocks! This was suburban Nottingham, so no idea how much space they had.
